Analysis of total lesion size at baseline and percentage of change in size in response to treatment in each of the 3 groups and Kruskal-Wallis test results for inter-group comparison
| Variables | Mean rank | Median | 25th–75th interquartile range | p-value | |
|---|---|---|---|---|---|
| Total lesion size at baseline in mm2 | Group A (n = 15) | 26.23 | 664 | 336.5–861 | 0.834 |
| Group B (n = 15) | 23.78 | 629 | 304.7–765.7 | ||
| Group C (n = 14) | 23.50 | 531.5 | 386.5–697.2 | ||
| Percentage of size change in response to treatment | Group A (n = 15) | 28.13a | 16.8 | 14.7–50.3 | < 0.001* |
| Group B (n = 15) | 29.40a | 31.6 | 17–37.06 | ||
| Group C (n = 14) | 9.07b | 2.04 | 0.76–2.04 | ||
* Significance level at p-value < 0.05; different superscript letters in the same column designate a statistically significant difference in pairwise comparison
